Laparoscopic Adjustable Gastric Banding (LAGB)

What is Laparoscopic Adjustable Gastric Banding?

Laparoscopic adjustable gastric banding (LAGB) or Laparoscopic Gastric banding is one of the least invasive weight loss surgery options. LAGB is performed as a laparoscopic surgery, with just a few small abdominal incisions, rather than one large cut. An adjustable band is put around the stomach to create a small pouch; thus you feel full even after eating a small quantity of food. The band can be tightened or loosened by your doctor by injecting or removing fluid into the port.

Why is it done?

Laparoscopic adjustable gastric banding is a weight loss surgery, suggested for individuals who have:

  • Tried non-surgical weight loss methods (such as dietary changes, medications etc.) without any long-term success.
  • BMI is greater than 40.
  • BMI is 35 with obesity related complications such as type 2 diabetes.

What happens during the procedure?

The procedure will be performed under general anaesthesia. Your surgeon will make small incision and insert instruments through theseincisions. Your surgeon will place an adjustable band around the upper part of your stomachand tighten it to form a small pouch. This creates a narrow passage for the food to move from the upper small pouch to the lower larger part of the stomach. A tube will be attached to the adjustable band. This tube is accessible through a port which is secured under the skin of your abdomen. Once procedure is completed, the incision site will be closed.

How long will it take?

The procedure usually takes 30 – 60 minutes depending upon your condition.

What happens after the procedure?

Post-surgery, you will be encouraged to walk to prevent blood clots. You will be given fluids and then be put on pureed food. Laparoscopic adjustable gastric banding generally requires 1 or 2 days stay at the hospital. You will be under a special diet which has to be followed strictly.Laparoscopic adjustable gastric banding limits the quantity of food that your stomach can hold, hence you don’t feel hungry even after eating only small amounts of food.Due to the narrow opening, food stays in the pouch for a longer time and you will also feel satisfied. This causes weight loss. However, this doesn’t reduce the absorption of calories and nutrients.Being an adjustable gastric band,your doctor might inject saline to make the band tighter or take out saline to loosen the band. Your weight loss and health condition will also be monitored on an out-patient basis.
